IMPROVED SUGAR-CANE PRESS.

Specification forming part of Letters Patent No. 46,781, dated March 14, 1865.

To all whom it may concern:

Be it known that I, J. C. Giusi/TAR, ot' Omaha City, in the county of Douglas and Territory of Nebraska, have invented a new and Improved Press, designed more especially for expressing juice from sugar-cane; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side elevation of my invention; Fig. 2, a vertical section of the same, taken in the line xx,Fig.3; Fig. 3, a horizontal section of the same, taken Vin line y y, Fig. l; Fig. 4, a vertical section of a portion ot the same, taken in the line z z, Fig; 3, Figs. 5, 6, and 7, views of the perforated tubes and cloth through which the juice escapes from the press-box. v

Similar letters of reference indicate like parts.

This invention relates to a new and improved arrangement of the press-box and plunger, as hereinafter fully shown and described, whereby the contents of the pressbox, after being subjected to the requisite pressure, may be emptied of the cheese or refuse with the greatest facility.

A represents a framing, composed of two upright posts, c a, attached to a suitable base, B, and connected at their upper ends by a cross-bar, b. C represents a frame, which is tted between the two posts a c of the framing A, and has vertical grooves c made in its sides to receive guides d at the inner sides of the posts c a, as shown in Fig. 3. This frame C is allowed to slide freely up and down in the framing A, and it has a pulley, D, at each side of it, around which ropes E E pass, one end of the latter being attached to the cross-bar b and the opposite end attached to a shaft, F, which passes horizontally through the upper parts of the posts a a ofthe framing A, as shown clearly in Fig. 1.

0n the frame O there is secured a bedpiece, G, in which the lower part, H, of the press-box is fitted. This part H of the pressbox is of inverted conical form, and it projects a short distance down below G, and has perforated tubes c f fitted in its bottom, said tubes being covered h in Fig. 2.

The upper part, I, of the press-box is placed on the bed-piece G and directly over the lower part, H, and is connected to the bedpiece by keys or wed ges IL, which pass through staples t', as shown in Fig. l, and to the crossbar b there are secured four pendants, jj, which have a circular plunger, J, secured to their lower end, said plunger just iitting the interior of the press-box. The upptr part, I, ofthe press-box has a ring, k, secured to each side of it, to which ropes l L are attached, said ropes, when in use, being connected to the shaft F.

Ihe sugar-cane or other substance to be operated upon is placed in the press-box, the upper part, I, being secured to the bed-piece Gdirectly over the lower part, I-I. The ropes E E are then attached to the shaft F and the latter turned, which causes the frame O to rise, and the substance within the press box is compressed in consequence of being drawn upward against the plunger J, the juice passing through the cloth g and perforated tubes e fand down into any receptacle prepared to receive it. After the juice is fully expressed from the substance within the press-box the ropes Z l, which are attached to the press-box, are connected to the shaft F, and the upper part, I, of the press-box detached from the lower part. The shaft F is then turned in a reverse direction, and the upper part, I, is raised alone and the contents of the press-box forced out from it.

Thus by this simple arrangement the sub-l stance in the pressbox may be compressed with the greatest facility, and the refuse, after the pressing operation, readily discharged from the press-box.

Having thusdescribed my invention, I claim as new and desire to secure by Letters Patent` The rising and falling frame O, in connection with the press-box, composed of two parts, I H, in combination with the fixed or stationary plunger J and shaft or windlass F, all arranged to operate substantially as and for the purpose herein set forth.
